if you see it on the memory then yeah, you can load it up. it's just a matter of selecting the right option. a screenshot would be mighty helpful as i don't have my fx here with me and i don't have any fx emulators. i can't try something here though i don't know if this message board will accept japanese font. many games usually give you the option to LOAD or CONTINUE and they would probably look like this in Japanese:
ロード or 続ける . Can you see that? They are usually in the lower end of the save/load menu. Get a s/s up or something and we'll take care of ya. good luck. that game is fun for sure.
